This paper describes CMU's entry for the Blizzard Challenge 2007. Our eventual system consisted of a hybrid statistical parameter generation system whose output was used to do acoustic unit selection. After testing a number of varied systems, this system proved the best in our internal tests. This paper also explains some of the limitations we see in our techniques. The CMU system is identified as D in the result charts.
